To all 'whom it may concern;

Be it knownthat I, OR'BIN F. SMITH, a resident of Ottumwa, in the county of VVa- ,pello and State of Iowa, hate invented certain new and useful imprei ements in Side- Delivery Rakes and Tedders, of which the following is a full, clear, and exact description;

The invention 'relates to side-delivery rakes andtedders. One object of the invention is to provlde a simple driving-connection for the crank shaft'for reciprocating the rake.

Another object of the invention.1s to pro vide an improved construction, whereby the forks may be readily reversed to 'act as tedder's when desired.

In side-delivery rakes of the class to which i the invention relates, it has heretofore been.

common, to provide an intermediate shaft comprising sections connectedby a universal joint, between the power wheel. or gear on one of the traction wheels and the crankshaft for operating the rakes; ortoprovide intermediate gearing or connections for the same purpose.

The resent lnvention desi ns to rovide a machine in which ajsingle intermediate and reversible together withthe gear onthe crank-shaft so that by reversing the relation of the shaft to the supporting-frame, the forks will be reversed to toss the hay, backwardlyto act as a tedder, and the crank shaft will be driven invopposite direction to that in which it is driven when it is used as a side-delivery rake by reason of the-rever sal of the gear with the shaft.

The invention consists in the several novel Specification of Letters Patent. Application filed. December 7, 1909. Serial No. 531,797. a

Fig. 5 is a detail plan of a portion of the crank-v shaft and the inner end of'the intermediate shaft with. the gears thereon, the parts he ing shown in position to operate the forks to rake the hay into wind'rows. Fig. 6 is a similar view, showing the parts organized to operate the crank-shaft in reverse direction so the? machine will operate as a tedder.

Fig. 7 isa section online 7-7 of Fig. 5.

Fig. 8 is asection online 8-.-8 of Fig. 5. -Fig'.'f9'is. a perspective'of the inner ends" of crank-shaft sections which are adapted to be coupled together. Fig. 10 is a detail sec tion through one of end-bearings for the crank-shaft. Fig. 11 is a section on line 1111 of Fig. 10.

The 'machine comprises a triangular frame constituted of a frdnt rail 10, a side rail 11 and a diagonal rail 12, which are secured together and this frame is supported and carried by a tractionovheel 13 at one side of the front thereof, a carrying-wheel 14 at the other side and a trail or caster wheel 15 at the rear. The caster-wheel 1.5 and carrying-wheel 14 areeach adjust-ably connected to the frame, so that the elevationof the frame, with respect to the ground, may be varied by suitable mechanism,'such as alever and rack in manner Well understood in the art. A short axle 17 is mounted in suitable brackets 18 and 19 secured to and depending from the frame, and extends laterally beyond the frame, .so that it will be carried in the hub of the traction-wheel 13 to sustain the frame. A drafttongue 20 is connected to the frame and a seat 21 is usually-provided for the' operator.

A'crank-shaft 22is mounted on the supporting-frame and 1s vprovided with a series ;of cranks 23., one for each fork to be operated. A tri-lateral frame 24comprising endbars 24* and a connecting barter; usually of angle-iron, is secured to the supportingframe and cross-bars 25, 26, 27 and 22 The crank-shaft is removably journaled at each end in a sectional box 29 secured to the frame 24 This shaft extends obliquely to the line of draft and the forks are disposed laterally and rearwardly of one another to successively toss the hay laterally and within the sweep of the next fork to cause the hay.

' to be delivered at the side of the machine in 'crank' 23 on shaft 22 and each of these forks a continuous'windrow. The crank-shaft is also-removably journaled in sectional boxles 29 which are secured to crosshars and 28. Theshaft is held against end-play by walls or abutments 29 on the outer sides journal-boxes 29 (Fig. 10) combined against endwise movement in the frame. A suitable fork is operated by each comprises a fork-head 31 on which springteeth'32 connected to and extending upwardly from the "fork-head. and a journal 34 on'the standard for the crank.- The upper end of each standard 33 is pivotally 5 connected to a lug 38 on the supportingframe. The cranks on shaft 22 are offset with respect to one another and when rotated cause the forks tobe 'reciprocated or raised and lowered to successively sweep over the ground- 'as the machine travels forwardly. The lower end of the teeth 32 are curvedto lift the hay from the ground and the fork thus tosses the hay laterally to the next series, the lastdelivering the hay in a windrow at the side of' the machine. The, mechanism for driving the crank-shaft to operate the forks, comprises an internally toothed gear-wheel 35, which is concentrically mounted with the tractionwheel 13, and driven thereby. An intermediate shaft 36 is provided at one end with a pinion 37 meshing with gear-wheel 35 and at itsother end-with a beveled gear '38 adapted to mesh with 'a beveled gear 39 on the. crank-shaft. in a journal 40 inbracket 1 9, which is se- Shaft 36 is mounted cured to railll of the supporting-frame by a bolt 46. Adjacent its otherend'shaft 36 is journaled in a bearing ina sectional bracket (t7, which is bolted toframe-bars 26 and 27. Bar 27 extends forwardly .of tri-lateral frame-bar 24 to bracket 19 which is secured to the rail 11 of the frame to provide a rigid frame-structure whereby the driven wheel 35 and the gear 39 on the tively secured against stresses which would retard rotation, this" bar 27 serving as an inclined cross-member which maintains the parts of the driving-connection in proper relation.

vwill be properly positioned to carry pinion 37 for-direct- -engagement with 'the teeth on the driving gear 35; Therefore, this shaft with a gear at each end serves to drive the crank-shaftdirectly, without the use of a universal joint 'or jntenniediate gear.v mechanism or a plurality of shafts.

The invention also designs to provide an improved machine in which, the forks are reversibly mounted and the (rank-shaft may be driven in opposite directions to cause these forks to not either as a side-dclivery rake or as a tedder. In order to facilitate conversion of the machine for use as a tedder, in lieu of a side-delivery rake,

the crank-shaft with the forks thereon reversible. to. bring-the forks in rearwardly facing relation to the frame, so they will deliver the hay 'rearwardly, instead of forwardly and laterally. By providing a reversiblescrank shaft, the forks may conveniently be brought to face rearwardly instead of forwardly and simultaneously the position of the gear 39 will be reversed with respect to gear 38 on the intermediate shaft 36 so that the crank-shafts and forks will be driven in opposite direction as a result of the reversal of the shaft without the interposition of'the reversing-gear and other mechanism. In order to'permit this re versal, each of the journal-boxes in which the shaft isjournaled is formed of sections so that the upperor cap section of each may be removed to permit removal of the shaft and reversal .thereof," that is, so that the front end oft-he shaft may be placed into v the rearrnost journal or vice versa. To permit this reversal of the forks, the upper ends thereof aregdetachably connected to the links 37, each of the latter having a pivot-terminal extending through a socket in the upper end-of the fork-standard 33 and held therein by a removable cotter-pin 52. The crank-shaft isusually of such length that it is inconvenient to handle for "reversal by a single person and to facili tate the reverslngoperation crank-shaft 22 is formed of sections 22 and 22 The hub ofgear 39 is extended to fit in a journal 54 formed in bracket 47; 'Bracket 47-comprises .a removable cap 54* and the extended hub, 39* of gear 39 isadapted'to receive the in-,

ner end of the shaft section 22 to keep "the shaft-sections alined. .A collar 55 is se-.

cured to shaft-section's 22 by a ,pin" 56 and is formed -With a pocket 57 adapted to receive a projecting ing 56 on the hub of gear 39 to operatively connect the shaft-see tions, so that one will bedriven with the other. End-bearings 29 hold' the shaft-sections together longitudinally. As aresult of this construction, theshaft maybe re versed in sections and more conveniently manipulated by one person.

Assuming the machine to be assembled for delivered in a substantially continuous wind-i row at' one side of the machine. When it is desired to use the-machine as a tedder (assuming the parts to be as shown in Fig. 1.), the shaft should be driven in opposite direction andvthe forks should be reversed to cause them to toss and lift the hay rear- Wardly Without successively delivering-the hayifrom one fork .into the sweep of the next. To effect such operation,. it is only necessary to remove'the caps of .the bearings in which the crank-shaft-is held" and "disconnect the upper ends of the'fork standards 33 by removingcotter-pins 52. The sections of the crank-shaft may be then separately removed, each .With the-forks connected thereto and reversely placed in theframe. By'thus reversing the crankshaft, gear-Wheel 39 will be brought into engagement With the opposite side of gear 38, so that Without the use of a reversing gear or additional gear mechanism, the shaft 'will be;

driven in reverse direction. IVhen the caps 1 of the iouignal-boxes for shaft- 22'have been replaced arid each of the links 37" have been connected to the upper end of one of the fork-standards, the machine will operate as a tedder, the crankshaft being driven in reverse direction and the forks facing rearwardly' to toss the hay rearwardly and laterally as the machine travels forwardly over the ground. v

The invention thus provides a simple driving Inechaism for the crank-shaft and simple mechanism for reversing the crank-shaft and forks in the frame to effectrotation thereof by the same mechanism,

The invention is.not to'be understood as restricted to the details shown and described,
